windowAttentionHandler: disconnect signals before destruction The 'destroy' signal is emitted at the end of the destroy() method. However the implementation of destroy() can end up emitting one of the signals we connect to on the window, causing us to re-enter destroy from its callback. That will in turn lead to some objects getting disposed twice, which produces a stack trace like the following one. This commit fixes the issue by overriding the destroy() method instead of connecting to the signal, which allows us to disconnect the signal handlers from the window at an earlier time and avoid re-entrancy. -- gnome-shell[1082]: Object Gio.Settings (0x7f0af8143f00), has been already deallocated — impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs. org.gnome.Shell.desktop[1082]: == Stack trace for context
